Abstract:
To evaluate the effect of probiotics and essential oils on gut activities and metabolic studies of broiler, this experiment was carried out on day-old broiler chicks of Ven-Cobb 400Y strain (n=240) for 42 days. These broiler chicks were randomly distributed into 4 equal treatment groups with T₀ (Control), T₁, T₂ and T₃ with 60 birds in each group having 4 replicates of 15 birds each group. The treatments were T₀ (Control, Standard broiler chicken diet as per BIS, 2007), T₁ (Standard broiler chicken diet as per BIS, 2007 with oregano essential oil @ 0.15 gm/kg diet), T₂ (Standard broiler chicken diet as per BIS, 2007 with probiotic (encapsulated Saccharomyces cerevisiae) @ 200 gm/ tonnes) and T₃ (Standard broiler chicken diet as per BIS, 2007 with oregano essential oil @ 0.15 gm/kg diet and probiotic (encapsulated Saccharomyces cerevisiae) @ 200 gm/ tonnes). In the gut salmonella and clostridia count, ileal pH, dry matter digestibility and nitrogen retention showed significant (P<0.05) difference while E Coli. count, intestinal length and weight do not show the significant (P>0.05) difference between the groups. So supplementation of probiotics and essential oils modulate the activity of gut, increase the dry matter digestibility and nitrogen retention of broiler chicken.
